If you've ever marvelled at gorgeous long-exposure shots of the night sky that seem to reveal every star in the heavens, you'll want to set aside part of your lunch break for photographer Kamil Tamiola's excellent 20 minute primer on how he captures such stunning imagery.

But his tips aren't for the feint of heart. While he touches on technical aspects of the camera and exposure settings, he also goes into detail about when and where are the ideal places to shoot. A full moon in the sky can help illuminate the surrounding landscape, but escaping the city to a higher and dryer elevation—like a mountain—will yield the best results. If you're bored with Instagram, this might be the ideal way to step up your photography game. [Vimeo via PetaPixel]
